What about supernatural photos?

The first category: artificial deliberate manufacturing: due to the great progress of photography technology, it is not too difficult to manipulate an ordinary photo to increase its interest. For example, Master Lang Jingshan, an internationally renowned photographer who just died, loves to play darkroom skills in addition to photography. It is not difficult to combine a negative of people, animals, trees and wonders with a strange Chinese painting style by repeated exposure in a darkroom. Because of its superb skills and artistic taste, it is highly respected, and everyone knows that it is a work of darkroom skills. It can be understood that it is not difficult to synthesize photos in a darkroom through repeated exposure. Of course, it is quite simple to synthesize "supernatural photos" if you have the heart. In the part of "artificial deliberate manufacturing", it can be subdivided into the following ways: repeated exposure in darkroom, repeated exposure in darkroom overlapping development camera, patchwork painting, perforation lighting, glass reflection synthesis, shutter speed, quick action of characters, and computer synthesis of special effects filters. The second category: the accidental effect of unintentional manufacturing: in fact, this part is the real focus of this article. In a series of recent religious paranormal fraud cases, apart from some deliberately created "paranormal photos" to cheat money and color, in various media, we have seen many believers put forward a large number of "paranormal photos" and even negatives, and swear that these photos are absolutely not fake, otherwise they can be tested and identified. I only saw these photos on TV. Personally, I think those photos are really different from "artificially fabricated supernatural photos" and are not deliberately made (I also believe that those believers are kind, pious and innocent), but those are still not really "supernatural photos", but almost 100% works that failed due to "accidental effect".
